Chapter 2: Overview
2. Overview
2.1 Introduction
The KVM Extender consists of a computer unit and a console (station) unit. It
allows you to place a keyboard/monitor/mouse up to 75 feet (23.4 meters) away
from a computer or KVM switch using an inexpensive Category 5 UTP (unshielded
twisted pair) cable. The extender provides an ideal and convenient way to remote-
ly access a computer located in a secure, clean or dirty, harsh environment.
The KVM Extender enables one user to control one computer, remotely. Use it
in factory or construction areas where you want to secure your computer and
valuable data or manage it remotely.
Use the extenders in a PS/2®or USB system. No software or DIP switches are
required, just plug and use. With one Status LED indicator and simple hotkey
commands, you can manage this device easily.
Two models are available. The ACU075A-USB allows one USB console to control
one USB computer via 1-to-2 cable. The ACU075A-PS2 enables one PS/2 console
to control one PS/2 computer via 1-to-3 cable.

Chapter 4: Configuration
4. Configuration
Before operating, adjust the video compensation. Use hotkeys to set the equal-
ization on the remote unit for an optimum video signal and its corresponding
cable length. The CAT5 cable can be one of five different lengths.
First, note the length of the RJ-45 cable you installed in Chapter 3. Then, use
the hotkeys to adjust the video compensation. Press Ctrl twice [Ctrl][Ctrl] followed
by the [Enter] key and the [F11] key. Different beeps indicate how long the
installed cable is. See Section 5.2.
Figure 4-1. Setting the video compensation screen.
NOTE: In standard mode press [Ctrl] [Ctrl], followed by [F11][F11]
In compatibility mode press [Ctrl][Ctrl], then press [Enter] and [F11].
To switch to a different mode, press [Ctrl] +[Ctrl], then press and hold [Alt] and
press [E].

ServSwitch Brand PS/2 and USB KVM Extender Kits
5. Operation
A keyboard and mouse must be connected to the console (station) unit. The
system then emulates the remote computer so that it can be controlled locally. Or,
you can also control the computer remotely.
5.1 LED Indicators
LEDs on the KVM Extender indicate the linking, communication, and control
between the computer unit and the console (station) unit.
When the console unit’s and the computer unit’s Status LEDs are both ON, the
console unit remotely controls the computer unit.
5.2 Hotkeys Control (Console Units Only)
Hotkey command is a short keyboard sequence to select a computer, to activate
computer scan, and so forth. The KVM Extender interprets keystrokes for hotkeys
all the time. A hotkey sequence starts with two left [Ctrl] keystrokes followed by
one or two more keystrokes. A built-in buzzer generates a high-pitched beep for
correct hotkey command, while one short and one long beep are sounded for
incorrect commands. Thus, the bad key commands will not be forwarded to the
selected modes.
There is a unique hotkey command of [Ctrl ] + [Ctrl] + [Alt] + [E] you should
be aware of when the KVM Extenders are connected to other KVM Switches.
To switch to this mode, press left Ctrl twice, hold Alt and press E key (press
both keys simultaneously). You can choose either the control mode of the KVM
Extender or the number of the computer connected to the KVM Switches.
NOTE: Hotkeys do not apply to the ACU075A-USB computer unit or to the
ACU075A-PS2 computer unit.
